    Default Problem with FileReader

    I have to make a program at which i have to read something from a file using FileReader.
    I write here the fragment of the code which reads an integer from the file :

    try
    		{
    			FileReader fr = new FileReader("C:\\Users\\nikipiulitza\\Desktop\\matrice.txt");
    			System.out.println(fr.read());
    			fr.close();
    		}
    		catch(Exception e )
    		{
    			System.out.println(e);
    		}

    In the matrice.txt file i have only written
    2
    And it reads 50 instead of 2....why ? Do i have to make another kind of files if i want to read integers from a file as they are written there ? .txt is not good ?

    Default Re: Problem with FileReader

    50 is the ASCII code of the character '2'

    try System.out.println((char)fr.read());
